The air conditioner will start in 3 minutes.
• Check that the power plug is properly connected. Insert the power plug into
the wall socket correctly.

Press the Temperature button on the remote control to change the set
temperature. Press the Temperature button to decrease or increase the
temperature.
• Check if the air filter is blocked by dirt.
• Check if the air conditioner has just been turned on. If so, wait 3 minutes. Cool
air does not come out to protect the compressor of the outdoor unit.
• Check if the air conditioner is installed in a place with a direct exposure to
sunlight. Hang curtains on windows to boost cooling efficiency.
• Check if the cover or any obstacle is not near the outdoor unit.
• Check if the refrigerant pipe is too long.
• Check if the air conditioner is only available in Cool mode.
